Online onboard scaling for Leaf spring suspension
In order to monitor load variations in these vehicles, a mechanism is installed on the vehicle to convert the elevation changes into angular variations and calculate the load weight based on calibration data.
Online onboard scaling for air spring suspension
Trailer trucks are usually equipped with this type of suspension system. We are using air pressure sensors to monitor load variations in these suspension, sensor output data is sent to the analog input of the tracking device. This information combined with location and other vehicle status are transmitted to central software and the load weight is calculated based on calibration data.
